SUMMARY

• Geological and geomechanical examinations allow to define the

geological structure of the deposit more precisely.

• Mine layout designs are set up and based on geomechanical

reconnaissance and geological model of the deposit. This allows

to minimalize the risk of unexpected events, increase the

resource recovery ratio and allows to predtict the quality of output

material.

• Mine production schedules are made upon created mine layout

design and geological models.
